| Topic | Function Transformations |
| Type | Single transformation application |
| Difficulty | Easy -1.3 This is a straightforward recall question testing basic transformations of functions. Each part requires only direct application of standard transformation rules (vertical translation adds to y, vertical stretch multiplies y, horizontal stretch divides x). No problem-solving or multi-step reasoning required—purely procedural with 1 mark per part indicating minimal complexity. |
